Cloud Storage - an introduction © EIT, Author Gay Robertson, 2017

History of Data Storage Computers have stored data using a range of different technologies over the years Originally, computer data was stored using punch cards which represented computer data Later Magnetic tape became the most popular method of storing data Over the years this technology has be used in the forms of Tape cassette, Floppy Disks and Hard Drives

Another common form of storage used is optical storage - this comes in the form of CDs, DVDs and Blu-Ray Disc More recently, Flash memory devices have gained in popularity, mostly in the form of removable storage such as Flash Drives and SD cards Now many computer manufactures are using Flash technology to make Hard Drives over Magnetic and optical forms of storage due to the much faster speeds and longer life for the device

Cloud storage Today, one of the quickest growing forms of storage is Cloud Storage Cloud Storage is not a physical storage device that you can walk into a shop and buy like you can with a Flash Drive or Hard Drive Instead companies offer Cloud Storage in a different location from you and your device, you store and access stored information through the use of internet technologies

Why use Cloud storage? Users/Companies store their data most commonly on the Hard Drive on their device Or they might have a server in their office building where data is stored, or multiple servers if they store a lot of data This can prove expensive if you are a small business, servers are very expensive for quality equipment Servers use a lot of power and require cooling to keep them functioning With this comes the need of specialized staff, space for the equipment, and software to manage all the processes

The idea of cloud technology is to eliminate all these requirements Instead of a company dealing with all these requirements, they can go to a cloud storage provider who has all this setup and simply charges an annual fee for storing data on their equipment Cloud technology still allows advantages of shared storage where multiple devices can access the same information

How does it work? Cloud Storage is not actually a cloud like some may think, instead Cloud Providers own and operate large sites with buildings containing large numbers of Servers These buildings are known as Data Centres Cloud Providers run much like an ISP or a Power Company A Cloud Provider purchases and sets up equipment and servers for storage This includes the power, cooling, and technical staff necessary for the site

Cloud providers then allow others to use and store data on their equipment for an annual fee This means a company or business can simply rent the storage and services they need instead of setting up expensive equipment themselves If an organization finds they need more storage or services they simply make an agreement with the Cloud provider and pay for the increased service Cloud Provider Company Office

Clients access these facilities through the use of the internet One Cloud Storage provider may have hundreds or even thousands of different organizations storing and accessing data from them Clients access these facilities through the use of the internet Cloud Provider

Cloud storage providers There are many cloud storage providers today Most commonly, both Google and Microsoft offer cloud storage through the use of Google Drive and OneDrive Some providers offer limited cloud storage for free when using their applications, such as free OneDrive storage when you create a Microsoft account

Many vendors charge a monthly subscription for additional storage space There are also private Cloud providers, these organizations are not so well known, but offer private cloud services to organizations and businesses Cloud Providers may be based globally and have Data centers across the globe, or some are based locally in their country of operation

Cloud Applications There are now a range of applications that use Cloud Technology to allow storage and synchronization of data across multiple devices For example you can now use an Online version of Microsoft Office for free with a Microsoft account Although these applications are more basic and don’t include all the features of the full software, it allows users to edit and create basic documents, spreadsheets, etc. online and stores the work on the user’s Cloud OneDrive Storage You are then able to access that data and online applications from any device (your Smartphone, Tablet – can be iOS or Android) providing you have access to the internet and work in real-time with other users collaborating on the development of the document, video, images, workbook etc etc
